Abstract

Systems, apparatuses, methods, and computer-readable media are provided for an access point (AP) for a wireless communication system operating in a licensed and an unlicensed spectrum. The AP includes processor circuitry configured to determine a plurality of interleaved interlaces based on a bandwidth of a physical uplink channel and a subcarrier spacing (SCS). The processor circuitry is configured to identify a plurality of resource blocks (RBs) corresponding to a first interleaved interlace of the plurality of interleaved interlaces, which are based on a number of subcarrier per RB. The processor circuitry is configured to allocate the plurality of RBs corresponding to the first interleaved interlace among one or more user equipments (UEs), and generate an indication of the allocated plurality of RBs, the first interleaved interlace, and the one or more UEs to transmit to the one or more UEs via radio front end circuitry coupled to the processor circuitry.

Claims (48)

1. An Access Point (AP), the AP comprising:

processor circuitry configured to:

determine a plurality of partial interleaved interlaces based on a bandwidth of a physical uplink channel and a subcarrier spacing (SCS);

identify a plurality of resource blocks (RBs) corresponding to a first partial interleaved interlace and a second partial interleaved interlace of the plurality of partial interleaved interlaces, wherein the plurality of RBs is based on a number of subcarriers per RB;

allocate the plurality of RBs corresponding to the first partial interleaved interlace and the second partial interleaved interlace among two or more user equipments (UEs); and

generate indications of the plurality of RBs, the first partial interleaved interlace and the second partial interleaved interlace, and the two or more UEs; and

radio front end circuitry, coupled to the processor circuitry, configured to:

transmit, to the two or more UEs, the indications of the plurality of RBs and the first partial interleaved interlace and the second partial interleaved interlace for the two or more UEs to transmit over the physical uplink channel.

2. The AP of claim 1 , wherein the processor circuitry is further configured to:

allocate the plurality of RBs, wherein at least one of the plurality of RBs is a fractional unit of a physical resource block (PRB).

3. The AP of claim 1 , wherein the processor circuitry is further configured to:

identify a different number of RBs corresponding to the second partial interleaved interlace compared to a number of the plurality of RBs corresponding to the first partial interleaved interlace.

4. The AP of claim 1 , wherein the bandwidth of the physical uplink channel corresponds to one or more listen-before-transmission (LBT) sub-bands acquired using an LBT procedure.

5. The AP of claim 1 , wherein the two or more UEs comprise a first UE and a second UE, wherein the first UE and the second UE are frequency division multiplexed, and

wherein the processor circuitry is further configured to unequally allocate the plurality of RBs to the first frequency division multiplexed UE and the second frequency division multiplexed UE.

6. The AP of claim 1 , wherein the indications are each a bitmap.

7. The AP of claim 6 , wherein a size of the bitmaps equals a number of the plurality of partial interleaved interlaces.

8. A method, comprising:

determining, by an access point (AP) for a wireless communication system, a plurality of partial interleaved interlaces based on a bandwidth of a physical uplink channel and a subcarrier spacing (SCS);

identifying, by the AP, a plurality of resource blocks (RBs) corresponding to a first partial interleaved interlace and a second partial interleaved interlace of the plurality of partial interleaved interlaces, wherein the plurality of RBs is based on a number of subcarriers per RB;

allocating, by the AP, the plurality of RBs corresponding to the first partial interleaved interlace and the second partial interleaved interlace among two or more user equipments (UEs);

generating, by the AP, indications of the plurality of RBs, the first partial interleaved interlace and the second partial interleaved interlace, and the two or more UEs; and

transmitting, from the AP to the two or more UEs, the indications of the plurality of RBs and the first partial interleaved interlace and the second partial interleaved interlace for the two or more UEs to transmit over the physical uplink channel.

9. The method of claim 8 , further comprising:

allocating, by the AP, the plurality of RBs, wherein at least one of the plurality of RBs is a fractional unit of a physical resource block (PRB).

10. The method of claim 8 , further comprising:

identifying, by the AP, a different number of RBs corresponding to the second partial interleaved interlace compared to a number of the plurality of RBs corresponding to the first partial interleaved interlace.

11. The method of claim 8 , wherein the bandwidth of the physical uplink channel corresponds to one or more listen-before-transmission (LBT) sub-bands acquired using an LBT procedure.

12. The method of claim 8 , wherein the two or more UEs comprise a first UE and a second UE, wherein the first UE and the second UE are frequency division multiplexed, and

the method further comprises allocating, by the AP, the plurality of RBs to the first frequency division multiplexed UE and the second frequency division multiplexed UE unequally.

13. The method of claim 8 , wherein the indications are each a bitmap.

14. The method of claim 13 , wherein a size of the bitmaps equals a number of the plurality of partial interleaved interlaces.

15. A non-transitory computer-readable media (CRM) comprising computer instructions, whereupon execution of the computer instructions by one or more processors of an access point (AP), causes the one or more processors to:

determine a plurality of partial interleaved interlaces based on a bandwidth of a physical uplink channel and a subcarrier spacing (SCS);

identify a plurality of resource blocks (RBs) corresponding to a first partial interleaved interlace and a second partial interleaved interlace of the plurality of partial interleaved interlaces, wherein the plurality of RBs is based on a number of subcarriers per RB;

allocate the plurality of RBs corresponding to the first partial interleaved interlace and the second partial interleaved interlace among two or more user equipments (UEs);

generate indications of the plurality of RBs, the first partial interleaved interlace and the second partial interleaved interlace, and the two or more UEs; and

transmit, to the two or more UEs, indications of the plurality of RBs and the first partial interleaved interlace and the second partial interleaved interlace for the two or more UEs to transmit over the physical uplink channel.

16. The non-transitory CRM of claim 15 , wherein, upon execution, the computer instructions further cause the one or more processors to:

allocate the plurality of RBs, wherein at least one of the plurality of RBs is a fractional unit of a physical resource block (PRB).

17. The non-transitory CRM of claim 15 , wherein, upon execution, the computer instructions further cause the one or more processors to:

identify a different number of RBs corresponding to a second partial interleaved interlace compared to a number of the plurality of RBs corresponding to the first partial interleaved interlace.

18. The non-transitory CRM of claim 15 , wherein the bandwidth of the physical uplink channel corresponds to one or more listen-before-transmission (LBT) sub-bands acquired using an LBT procedure.
